History

TiddlyWiki was first released 10 years ago (before jQuery!).

TiddlyWiki5 began in 2011, and is currently in beta: https://github.com/Jermolene/TiddlyWiki5

What is TiddlyWiki?

TiddlyWiki is a JavaScript wiki that can run entirely in the browser, or under Node.js.

Features

• Works on pretty much any HTML5 browser
• Built-in encryption
• Multi-language support for the user interface and your content
• (Responsive) themes
• Colour palettes
• Plugins for popular JS libraries:
  • CodeMirror
  • D3.js
  • Highlight.js
  • MarkDown
• Pluggable navigation visualisations

How TiddlyWiki Saves Changes

The awkward but HTML5-compliant way:

var link = document.createElement("a");
link.setAttribute("target","_blank");
link.setAttribute("href","data:text/html," + encodeURIComponent(text));
link.setAttribute("download",filename);
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

Saving with TiddlyFox

Allows changes to be saved directly to the file system in Firefox (including Firefox for Android).

Saving with TiddlyDesktop

TiddlyDesktop is a custom browser with extensions to support working with TiddlyWiki. Based on node-webkit.

Saving on iPad/iPhone

Demo of Single File Edition

You're already in a demo of TiddlyWiki, but here's a quick run through of using it:

1. Visit http://tiddlywiki.com/empty.html in Chrome
2. Add and edit some tiddlers
3. Explore tags, search, sidebars
4. Drag an image from the file system
5. Copy and paste part of an HTML page
6. Save using Chrome
7. Inspect source
8. Reload in Firefox, use TiddlyFox
9. Enable encryption, resave, check source

Task Management Demo

<$list filter="[!has[draft.of]tag[task]!tag[done]sort[created]]">

<$checkbox tag="done"> <$link to={{!!title}}><$view field="title"/></$link></$checkbox>

</$list>

See http://tiddlywiki.com/#TaskManagementExample

Customisation via System Tags

Demo of customising TiddlyWiki:

1. Create a tiddler called MyMenu
2. Tag it $:/tags/SideBar and give it the text of some menu items
3. Add a caption field
4. Add a list-before field
5. Same for adding a tab to $:/ControlPanel

Serverlessness FTW!

Individual freedom on the Internet is threatened by the behaviour of corporations and the Governments that subvert them.

How can we make an independent web? It's fundamentally asymmetrical; only brave homesteaders run their own servers, most people are happy to rent space from a central service.

The jump to running your own server is huge: it's a new cost for most people, and the benefit is intangible. It's one of those situations where the penalties for screwing up can be disproportionate: eg, failing to keep backups or to keep security software up to date.

Duality of TiddlyWiki

Tiddly === Everything is a tiddler

A tiddler is defined as the smallest semantic unit of information.

It is a structure optimised for reuse through aggregation and composition.

Wiki === Everything is wikification

Wikification is the process of converting WikiText into HTML.

It makes linking (and other hypertext operations) become part of the punctuation of writing.

Everything is a Tiddler

It's tiddlers, all the way down. The tiddler model is used for:

• User text and data
• JavaScript CommonJS-compatible modules
• User interface state
• Configuration eg
  • Settings $:/config/Navigation/UpdateAddressBar
  • Editor type mappings $:/config/EditorTypeMappings/image/gif
• Plugins:
  • Core code
  • Themes
  • Languages
  • Plain plugins
• Test specifications

The boot kernel brings up enough of the infrastructure to load plugins. The core code itself is a plugin.

TiddlyWiki Rendering Pipeline

Like Angular and Ractive. Not string based; always uses a DOM and selective updating.

User Interface State

Show how sidebar state is held in $:/state/sidebar:

$tw.wiki.addTiddler(new $tw.Tiddler({title: "$:/state/sidebar",text: "yes"}))

Basic primitives for user interfaces:

• <$transclude> widget to transclude another tiddler
• <$reveal> widget to selectively show or hide content according to a state tiddler
• <$button> widget set or toggle a state tiddler
• <$list> widget to repeat a template for each of several tiddlers

Running TiddlyWiki Under Node.js

Creating a single file wiki

tiddlywiki mywiki --init tw5.com
tiddlywiki mywiki --rendertiddler $:/core/save/all index.html text/plain

See the template for the HTML, and for some of the CSS.

Serving a wiki over HTTP

tiddlywiki my2wiki --init server
tiddlywiki my2wiki --server

TiddlyWiki5 provides a TiddlyWeb-compatible API

Static Site Generation

tiddlywiki ./myWiki \
--rendertiddler $:/core/templates/static.template.html static.html text/plain \
--rendertiddler $:/core/templates/alltiddlers.template.html alltiddlers.html text/plain \
--rendertiddlers [!is[system]] $:/core/templates/static.tiddler.html static text/plain \
--rendertiddler $:/core/templates/static.template.css static/static.css text/plain

alltiddlers.html

static/AllTiddlers.html

TiddlyWiki Server Synchronisation

The same syncer module is used in the browser and the server.

Using TiddlyWiki as a Library

/*

A sample node.js application that uses TiddlyWiki5 as a library

*/

var $tw = {};

require("../TiddlyWiki5/boot/bootprefix.js").bootprefix($tw)

// Dummy command line arguments telling TW5 not to load a wiki from the filesystem
$tw.boot = $tw.boot || {};
$tw.boot.argv = ["*"];

require("../TiddlyWiki5/boot/boot.js").TiddlyWiki($tw);

// Boot TiddlyWiki
$tw.boot.boot();

// Add some tiddlers
$tw.wiki.addTiddler({
		title: "TiddlerOne",
		text: "Text of tiddler one, incorporating the {{TiddlerTwo}}",
		tags: ["alpha", "beta"]
});
$tw.wiki.addTiddler({
		title: "TiddlerTwo",
		text: "Text of tiddler two"
});

// Render a tiddler as HTML
var html = $tw.wiki.renderTiddler("text/html","TiddlerOne");
console.log(html);

10 years of TiddlyWiki

I've learned:

• JS was wildly misunderstood. It's still widely misunderstood
• Browsers were broken; now they're pretty consistent (except certain areas like drag and drop)
• My privilege is to be in a position to engage with my users to understand their needs. I should be paying people in the community for what I learn about making TiddlyWiki better
• Open source is the natural state of human software production
  • It recognises that software is not a branch of engineering
  • It teaches us how to make collaboration be a by-product of performing the work. It allows us to present the largest possible surface area for prospective collaborators.
• Being a software designer isn't enough. We need to design business models that are healthy for us, and in the best interests of our users. Something as personal and fundamental as my intellectual apparatus shouldn't be under the control of someone else
